'ro ALL wHoM I'r MAY costosas;

Seit known 'that I, GRSAMFS HOLMES, o New Lenox, in the county of Will, and State oi' Illinois, have invented new and useful l'mprr't'ements in 'Grain-'Separatore for T hreshing-Machines; and I (lo hereby declare that the following is a full, clear, and exact description thereof, which will enable others skilled in'the art to make/and use the same, reference being had tc the accompanying drawings forming part of this specification.

This invention relates more particularly to improvcmentsupon a grain-separator for threshiixgmaehiues, embraced in Letters Patent granted to me on the 31st day of January, A. D. 1865, and it consists, first, in af novel construction or formation of the'oor of the straw-shoe or carrier-frame, whereby the threshed grain carried forward by the forward longitudinal shaking or tossing motion ot' the said` shoeor carrier will be retained or held in such forward position upon the backward stroke or play of the carrier-frame, and not, asv heretofore, carried partially back by the same-the importance of which result is obvious; second, in connecting the straw-shoe or carrier and the grain or an-shoe together, in such a manner as to operate simultaneously or together; and third, in a peculiar manner oi supporting or suspending both the straw and grain-shoes, es will be hereinafter particularly described.

In the accompanying plate of drawings my improvements in `,grain-threshing machines are illustrated- Figure Einheing an elevation of one side of the machine, l

A, in the drawings, represents the supporting framework lofthe machine, which may be of any suitable form `and construction to accommodate and receive its. working parts. B, the straw-sl1oe-or carrier, placed inend between the two side frames C of the framework, so that it can move or play forward and backwardtherein. This carrier extends in the direction of the length ctv-the frames, and by an' arm, D, is secured to its under side. It is connectedwith and hung upon the crank-arm E of the horizontal transverse driving-shaft F of the machine, arranged to turn in suitable bearings of the 'framework A. The floor G of the lstraw-shoe 'orc'a rricr, for its entire length, and at equal distances apart' in the present instance, is similarly notched or toothed across its width, as plainly shown in longitudinal section in iig. 2, and is also provided with a series of parallel longitudinal partition-plates, H, all of ivhich extend beyond the louter end oi", the shoe to-an equoldist'nncc, andhaye their upper edge L notched or toothed similar and corresponding to that ot" the lloor of the shoc.' These partitions H termina-te a .short distance from the inner end of or that end wherethe grain is delivered to the shoe from the threshing-machine proper, gradually decreasing in height until they'are even, or nearly so, with the surface of the shoe-floor. By the notches of the floor of the straw-shoe or carrierit is. plainly evident that theywill serve to hold or retain, to a great degree or extentpthe grain and straw iny the position to which they are thrownv forward by the forward movement of the carrier, and thus prevent them from being carried backwardltherebyas the shoe moves back, the importance of which is obvious, and needs noparticular mention herein. The inner end of the straw-shoe or carrier is suspended to each side of'tho side frames' B through vertically-inclined conn'ecting levers or bars, N, that at their upper ends are pivoted to. the side'poces of the saidl shoe or carrei'gsnd at their lower ends to the framework A. Tolthe outer -end of the straw-shoe' or carrier, and 'upn each `s ide of the sama-the upper ends of inclined vertical levers or bars, S, are pivotod, *that at their lower'endsare pivoted to the inner end of eachV side ot' the-grain-slloe orframe T, and between their endsare'huug upon fulcrum-pins U of the lframework This grain-shoe '.l, at its outer end, is suspended through levers; V, pivoted thereto, at their lower ends, to the framework A, -to 'whichthoy are alsopivoted at their upperjends. By the above-described connection between the grain-shoe and the st rew-sh'cc o r carrier, it is plainly obvious that ltheir movements will be simultaneous and together.

What I claim as new, and desireto secure by Letters Patent, is The hars S, pivoted near their centres, U, tothe frame of themachinc, and supporting the strnwyshoe B, their lower ends pivoted to the grain-shoe '.l, whose outer end is supported by theipivoted-bars V, all arranged as described, whereby the movements oi' the strano-shoe B and grain-shoe '1 are" simultaneous, as hereinset f thf th ses eoitied.-
